Second Grade Reading Unit - Taking Charge of Reading. All of the work in this document is based on the work of Lucy Calkins. The unit is written with overview, assessment information, getting ready for unit, and teaching points. This unit will give you all of the teaching points for each bend along with idea for modeling or possible chart that could be made with the unit. It has been designed so that the teacher can put their own spin on the lesson. Any suggestions for improvement would be appreciated.
